Referring to FIGS. 1 and 2, the one or more memories 26 may storeprocessor executable code and/or information comprising a structuredatabase 32, one or more images databases 34, and program logic 36. Theprocessor executable code may be stored as a data structure, such as adatabase and/or a data table, for example. In some embodiments, one ormore memories of the user terminal 14 may include a structure database32, one or more image databases 34 and program logic 36 as described infurther detail herein.

The structure database 32 may include information (e.g., location, GISdata) about the structure of interest. For example, the structuredatabase 32 may store identification information about the structureincluding, but not limited to, address, geographic location,latitude/longitude, and/or the like.

The one or more memories 26 may include one or more image databases 34.The one or more image databases 34 may store geo-referenced imagery.Such imagery may be represented by a single pixel map, and/or by aseries of tiled pixel maps that when aggregated recreate the image pixelmap. Imagery may include nadir, ortho-rectified and/or obliquegeo-referenced images. The one or more processors 24 may provide theimages via the image database 34 to users at the one or more userterminals 14. In some embodiments, one or more image databases 34 may beincluded within the user terminals 14.

The one or more memories 26 may further store processor executable codeand/or instructions, which may comprise the program logic 36. Theprogram logic 36 may comprise processor executable instructions and/orcode, which when executed by the processor 24, may cause the processor24 to execute image display and analysis software to generate, maintain,provide, and/or host a website providing one or more structureevaluation requests, for example. The program logic 36 may further causethe processor 24 to collect identification information about thestructure of interest 21 (e.g., address), allow one or more users tovalidate a location of the structure, obtain geographical positions ofthe structure, and the like, as described herein.

Referring to FIG. 3, shown therein is an exemplary flow chart 40 ofprogram logic 36 for creating a structure evaluation report according tothe instant disclosure. Program logic 36 may comprise executable code,which when executed by the one or more processors 24 may cause the oneor more processors 24 to execute one or more of the following steps.

In a step 42, the one or more host systems 12 may receive identificationinformation of the structure from the user terminal 14. For example, theone or more host systems 12 may receive the address of the structure,geographic location of the structure (e.g., X, Y, Z coordinates,latitude/longitude coordinates), a location of the user terminal 14determined by a Geographic Position System (GPS) and/or the like.

In some embodiments, the user may validate the location of the structureof interest 21. One or more processor 24 may provide one or more imagesvia the image database 34 to the display unit 22 of the user terminal14. For example, FIG. 4 illustrates an exemplary screen shot 60 of anoblique image 62 of the structure of interest 21 that may be displayedon the display unit 22 of the user terminal 14, shown in the blockdiagram of FIG. 1. The one or more images 62 may be geo-referencedimages illustrating portions or all of the structure of interest 21.Referring to FIGS. 1 and 4, the program logic 36 may cause the processor24 to provide users the one or more geo-referenced images 62 (e.g., viathe display unit 22), and allow the user to validate the location of thestructure of interest 21 (e.g., via the input unit 20). For example, theuser may be able to use a drag-and-drop element provided by the programlogic 36 via user terminal 14 to select the structure of interest 21within the one or more geo-referenced images 62. Selection of thestructure of interest 21 within the one or more geo-referenced images 62may provide one or more validated images and a validated location of thestructure of interest. It should be noted, that in some embodiments, theprogram logic of the user terminal 14, with or in lieu of the programlogic 36 of the processor 24, may provide users the one or moregeo-referenced images 62 to allow for validation of the location of thestructure of interest 21.

In some embodiments, validation of the geo-referenced images may beprovided by one or more additional host systems via the one or moreprocessors 24 in lieu of, or in combination with host system 12. Forexample, the host system 12 may direct the user to a second host systemwherein one or more processors of the second host system may providegeo-referenced images 62 from image database to the user for validationof one or more structures of interest 21.

In some embodiments, the geographic location may include coordinates,and validation of the geographic location may be provided by the user byaltering one or more coordinates of the geographic location. Users mayalter the one or more coordinates by methods including, but not limitedto, manual manipulation, drag-and-drop elements, and the like.

In some embodiments, location of the structure of interest 21 may beautomatically determined by location of the user terminal 14. Forexample, a user may be physically present at the structure of interest21, and the user may be holding the user terminal 14 which determinesits location using any suitable technology, such as GPS. Using locationcoordinates of the user terminal 14, the location of the structure ofinterest 21 may be determined.

In a step 44, a footprint of the structure of interest 21 may bedetermined. The footprint may provide a two-dimensional boundary (e.g.,sides) and/or outline of the structure of interest 21. For example, theoutline of the structure of interest 21 may be determined using systemsand methods including, but not limited to, those described in U.S.Patent Publication No. 2010/0179787, now U.S. Pat. No. 8,145,578; U.S.Patent Publication No. 2010/0110074, now U.S. Pat. No. 8,170,840; U.S.Patent Publication No. 2010/0114537, now U.S. Pat. No. 8,209,152; U.S.Patent Publication No. 2011/0187713; U.S. Pat. No. 8,078,436; and U.S.Ser. No. 12/909,692, now U.S. Pat. No. 8,977,520; all of which areincorporated by reference herein in their entirety. In some embodiments,the footprint of the structure of interest 21 may be provided to theuser via the display unit 22. For example, in some embodiments, thefootprint of the structure of interest 21 may be displayed as a layer onone or more images (e.g., nadir image) via the display unit 22.

In some embodiments, the one or more processors 24 may provide, via thedisplay unit 22, one or more websites to the user for evaluation ofmultiple oblique images to provide the footprint of the structure ofinterest 21. For example, the user and/or the processors 24 may identifyedges of the structure of interest 21. Two-dimensional and/orthree-dimensional information regarding the edges (e.g., position,orientation, and/or length) may be obtained from the images using userselection of points within the images and the techniques taught in U.S.Pat. No. 7,424,133, and/or stereo-photogrammetry. Using thetwo-dimensional and/or three-dimensional information (e.g., positionorientation, and/or length), line segments may be determined withmultiple line segments forming at least a portion of the footprint ofthe structure of interest 21.

In a step 46, data indicative of geographic positions pertaining to thefootprint of the structure of interest 21 and/or structure heightinformation may be obtained. For example, in some embodiments, theheight of structure of interest 21 above the ground may be determined.The height of the structure of interest 21 above the ground may aid indetermining altitude for the flight plan of the unmanned aircraft 18 asdiscussed in further detail herein. Measurements of the geographicpositions of the structure of interest 21, such as a vertical structure,may include techniques as described in U.S. Pat. No. 7,424,133, which ishereby incorporated herein by reference in its entirety. The term“vertical structures”, as used herein includes structures that have atleast one portion of one surface that is not fully horizontal. Forexample, “vertical structures” as described herein includes structuresthat are fully vertical and structures that are not fully vertical, suchas structures that are pitched at an angle and/or that drop into theground. The side of a structure is not limited to only one or more wallsof the structure of interest 21, but may include all visible parts ofthe structure of interest 21 from one viewpoint. For instance, when thepresent disclosure is discussing a structure of interest 21, such as ahouse, a “side” or “vertical side” includes the wall of the house andthe roof above the wall up to the highest point on the house.

In some embodiments, more than one height may be used. For example, ifthe structure of interest 21 is a split-level building having a singlestory part and a two story part, a first height may be determined forthe first story and a second height may be determined for the secondstory. Altitude for the flight path of the unmanned aircraft 18 may varybased on the differing heights of the structure of interest 21.

In some embodiments, using the input unit 20 and/or the display unit 22,the user may give additional details regarding geographic positionspertaining to the outline of the structure of interest 21 and/orstructure height information. For example, if the structure of interest21 is a roof of a building, the user may include identification of areassuch as eaves, drip edges, ridges, and/or the like. Additionally, theuser may manually give values for pitch, distance, angle, and/or thelike. Alternatively, the one or more processors 24 may evaluate imageryand determine areas including eaves, drip edges, ridges and/or the likewithout manual input of the user.

In a step 48, using the footprint, height, and possibly additionalgeographic positions or information pertaining to the structure ofinterest 21 including the geographic location of obstructions inpotential flight paths such as trees and utility wires, unmannedaircraft information may be generated by the one or more host systems 12and/or the user terminal 14. The unmanned aircraft information mayinclude flight path information, camera control information, and/orgimbal control information.

Flight path information may be configured to direct the unmannedaircraft 18 to fly a flight path around the structure of interest 21. Insome embodiments, a flight path may be displayed to the user on one ormore images (e.g., nadir, oblique) via the display unit 22. For example,FIG. 6 illustrates an exemplary screen shot 66 of a nadir image 68showing a flight path 70 about the structure of interest 21. In someembodiments, the flight path 70 may be a displayed as a layeroverlapping the nadir image 68 of the structure of interest 21 on thedisplay unit 22 of FIG. 1.

Generally, the flight path information directs the unmanned aircraft 18in three dimensions. Referring to FIGS. 5 and 6, the flight pathinformation may be determined such that the flight path 70 around thestructure of interest 21 is laterally and/or vertically offset from thegeographic positions of the outline of the structure of interest 21. Inparticular, lateral offset L_(OFFSET) and vertical offset V_(OFFSET) maybe dependent upon the height H of the structure 21, orientation of thecamera relative to the unmanned aircraft 18, and characteristics of thecamera 19.

Referring to FIG. 5, generally in determining offset from the structure21, the field of view (FOV) of the camera 19 may be positioned such thata center C₁ is at one half the height H of the structure 21, forexample. Additionally, one or more buffer regions B may be added to theFOV. Buffer regions B may increase the angle of the FOV by a percentage.For example, buffer regions B₁ and B₂ illustrated in FIG. 5 may increasethe angle of the FOV by 20-50%. To determine the lateral offsetL_(OFFSET) and the vertical offset V_(OFFSET) of the camera 19 from thestructure 21, a predetermined angle Θ within a range of 25-75 degreesmay be set. Once the angle Θ is set, the lateral offset L_(OFFSET) andthe vertical offset V_(OFFSET) of the camera 19 relative to thestructure 21 may be determined using trigonometric principles, forexample. For example, lateral offset L_(OFFSET) may be determined basedon the following equation:L _(OFFSET) =C ₁*Sin(Θ)  (EQ. 1)wherein C₁ is the centerline of the field of view FOV. The verticaloffset V_(OFFSET) may be determined based on the following equation:V _(OFFSET) =C ₁*Cos(Θ)  (EQ. 2)

wherein C₁ is the centerline of the field of view FOV.

The flight path information may optionally direct the roll, pitch andyaw of the unmanned aircraft 18. For example, some versions of theunmanned aircraft 18 may not have a multi-axis gimbal and as such, canbe directed to aim the camera 19 by changing the yaw, pitch or roll ofthe unmanned aircraft 18. The current yaw, pitch and roll of theunmanned aircraft 18 may be measured using a position and orientationsystem that is a part of the unmanned aircraft 18. In some embodiments,the position and orientation system may be implemented usingmicroelectromechanical based accelerometers and/ormicroelectromechanical based gyrometers.

In many cases, there may be obstacles that lie along the flight path.Some of those obstacles may be able to be detected by the system throughuse of the imagery. In some embodiments, the flight path 70 may bedetermined such that interference with outside elements (e.g., trees andtelephone wires) may be minimized. For example, FIG. 7 illustrates avariation of the flight path 70 determined in FIG. 4 wherein the flightpath 70 a of FIG. 7 minimizes interference by following the outline ofthe structure of interest 21.

A ground confidence map, as described in U.S. Pat. No. 8,588,547, whichdisclosure is hereby incorporated herein by reference, could be used toidentify objects for which there is a high degree of confidence that theobject lies elevated off of the ground. Auto-correlation and auto-aerialtriangulation methods could then be used to determine the heights ofthese potential obstructions. If the flight path would go through one ofthese obstructions, it could be flagged and the algorithm could thenattempt to find the best solution for getting past the obstructions:either flying closer to the structure of interest 21 as shown in FIG. 7,which might necessitate additional passes due to a finer resolution andtherefore smaller path width, or by flying over the obstruction andaiming the camera 19 at a steeper oblique angle, which again may requirean adjustment to the flight path to ensure full coverage. For any flightpaths that are flagged for possible obstructions, a system operatorcould validate the corrective route chosen and alter it as necessary.

In addition to those obstacles that are identified within the image,there may also be obstacles that cannot be identified in the image.These could be newer trees or structures that were not in the originalimages used for flight planning, wires or other objects that may notshow up in the images in enough detail to be able to determine theirlocation, or other unexpected obstacles. As such, the unmanned aircraft18 may also incorporate a collision detection and avoidance system insome embodiments. The collision detection and avoidance system couldeither be imaging based, or active sensor based. When an obstacle liesalong the Flight Path, the software guiding the unmanned aircraft 18could first attempt to move closer to the structure of interest 21 alongthe path from the Flight Path to the Target Path. If after a suitablethreshold, which may be set at 10% of the distance (104′ in the aboveexamples, so 10% being 10.4′) so that the 20% overlap still ensurescomplete coverage, if the unmanned aircraft 18 is unable to bypass theobstacle, the collision detection and avoidance system would steer theunmanned aircraft 18 back to its original point of collision detectionand would then attempt to fly above the obstacle.

Since the software controlling the unmanned aircraft 18 keeps the camera19 aimed at the Target Path, flying higher may still capture thenecessary portions of the structure of interest 21; but the obliquedown-look angle may change and the resolution may become a bit coarser.In extreme circumstances, the unmanned aircraft 18 may require operatorintervention to properly negotiate around the obstacle. In these cases,the software running on a processor of the unmanned aircraft 18 wouldtransmit a signal to the operator in the form of an audible alarm, forexample, and allow the operator to steer the unmanned aircraft 18 aroundthe obstacle. As the unmanned aircraft 18 passes the Flight CapturePoints, the camera(s) 19 would fire. To ensure this, the Flight CapturePoints are not just points, but may be a vertical plane that isperpendicular to the Flight Path and that passes through the FlightCapture Point. Thus, even if the unmanned aircraft 18 is 30′ above oraway from the Flight Path at the time, as it passes through that plane,and thus over or to the side of the Flight Capture Point, the softwarecontrolling the unmanned aircraft 18 would cause the camera 19 to fire.

The camera control information may be loaded into the software runningon the processor of the unmanned aircraft 18 to control actuation of thecamera 19 of the unmanned aircraft 18. For example, the camera controlinformation may direct the camera 19 to capture images (e.g., obliqueimages) at one or more predefined geographic locations 74 (which arereferred to herein below as Flight Capture Points), as illustrated inscreen shot 72 of FIG. 8. In some embodiments, the camera controlinformation may direct the camera 19 to capture images on a schedule(e.g., periodic, random). Further, the camera control information maycontrol camera parameters including, but not limited to zoom, focallength, exposure control and/or the like.

The gimbal control information may be loaded into the software runningon the processor of the unmanned aircraft 18 to control the direction ofthe camera 19 relative to the structure of interest 21. For example, thegimbal control information may control the orientation of the camera 19in three dimensions such that during capture of an image, the camera 19is aligned with a pre-determined location on the structure of interest21 that are referred to below as Target Capture Points.

In a step 50, the unmanned aircraft information may be stored on one ormore non-transitory computer readable medium of the host system 12and/or user terminal 14. For example, in some embodiments, the hostsystem 12 may determine the unmanned aircraft information, communicatethe unmanned aircraft information to the user terminal 14 via thenetwork 16, such that the unmanned aircraft information may be stored onone or more non-transitory computer readable medium. Alternatively, theuser terminal 14 may determine the unmanned aircraft information andstore the unmanned aircraft information on one or more non-transitorycomputer readable medium. In some embodiments, the one or morenon-transitory computer readable medium may include a USB flash drive orother similar data storage device.

In a step 52, the unmanned aircraft information may be loaded onto theunmanned aircraft 18. For example, the unmanned aircraft information maythen be loaded onto the unmanned aircraft 18 via transfer of thenon-transitory computer readable medium (e.g., USB flash drive) from theuser terminal 14. It should be noted that the unmanned aircraftinformation may be loaded and/or stored onto the unmanned aircraft 18 byany communication, including communication via the network 16.

The unmanned aircraft 18 may use the unmanned aircraft information tocapture one or more oblique images of the structure of interest 21.Generally, the unmanned aircraft 18 may follow the flight path withinthe unmanned aircraft information obtaining the one or more obliqueimages as set out within the camera control information and gimbalcontrol information. In some embodiments, a user may manually manipulatethe flight path 70 of the unmanned aircraft information during flight ofthe unmanned aircraft 18. For example, the user may request the unmannedaircraft 18 to add an additional flight path 70 or repeat the sameflight path 70 to obtain additional images.

In a step 54, the one or more processors 24 may receive one or moreoblique images captured by the unmanned aircraft 18. The flight pathinformation, camera control information and gimbal control informationmay direct the unmanned aircraft 18 to capture one or more obliqueimages at predetermined locations and times as described herein. The oneor more oblique images may be communicated to the one or more processors24 via the network and/or stored one or more non-transitory computerreadable medium. The one or more oblique images may be stored in one ormore image database 34. In some embodiments, the one or more obliqueimages may be communicated to the user terminal 14, and the userterminal 14 may communicate the images to the one or more processors 24.

In a step 56, the one or more processors 24 may generate a structurereport. The program logic 36 may provide for one or more user terminals14 interfacing with the processor 24 over the network 16 to provide oneor more structure report website pages allowing users to view thestructure report. For example, FIG. 9 illustrates an exemplary screenshot 76 of a structure report 78 on the display unit 22 of a userterminal 14.

One or more images 80 obtained from the camera 19 of the unmannedaircraft 18 may be used for evaluation of the structure of interest 21for the structure report 78. For example, if the structure of interest21 is a building, the images obtained from the camera 19 may be used inan insurance evaluation (e.g., flood damage, hail damage, tornadodamage).

One or more images 80 obtained from the camera may be provided in thestructure report 78. For example, the structure report 78 in FIG. 9includes an image data set 82. The image data set 82 may include nadirand/or oblique images 80 of the structure of interest 21. Additionally,the image data set 82 may include one or more images 80 of objects ofinterest on and/or within the structure of interest 21. For example, ifthe structure report 78 details damage to a roof of the structure ofinterest 21, one or more images 80 of damage to the roof may be includedwithin the image data set 82. In some embodiments, third party images ofthe structure of interest 21 may be included within the structure report78.

Structural details may be provided in the structure report 78 within astructure data set 84 as illustrated in FIG. 9. The structure data set84 may include information related to structure of interest 21including, but not limited to, area of the structure of interest 21(e.g., square feet), roof details (e.g., pitch, ridge length, valleylength, eave length, rake length), height of the structure of interest21, and/or the like. Additionally, the structure data set 84 may includeorder information for the structure report 78. For example, thestructure data set 84 may include information regarding the time anorder for the structure report 78 was placed, the time the order for thestructure report 78 was completed, the delivery mechanism for thestructure report 78, the price of the order for the structure report 78,and/or the like, for example.

Based on the flight path information, camera control information, andgimbal control information, during image capture, the location of thecamera 19 relative to the structure of interest 21 for images capturedmay also be known. For example, in some embodiments, the X, Y, Zlocation (e.g., latitude, longitude, and altitude) of a location seenwithin each image may be determined. The information may be used tofurther evaluate objects on and/or within the structure of interest 21.In some embodiments, images 80 captured by the unmanned aircraft 18 maybe used to generate a two or three-dimensional model of the structure ofinterest 21.

The unmanned aircraft structure evaluation system 10 may be used asfollows.

An insurance adjustor or other field operator would arrive at the housebeing assessed for damage or for underwriting. He would go to an onlineapplication on a portable networked computer device (e.g., user terminal14), such as a tablet, smart phone, or laptop, and select the propertyand structure of interest 21. This selection could be done withidentification information, such as a GPS determining his currentlocation, through entering a street address into the search bar, throughentering the geographic location into the user terminal 14, throughscrolling on a map or aerial image displayed on the user terminal 14 ofthe current location, or through a preselected target property made byvirtually any method that results in finding the property and storing itfor later retrieval.

Once the location is found, an image or 3-D Model for that property andstructure of interest 21 is displayed on the screen. An oblique image,or a street side image, would provide more information to the operatorfor property verification as traditional orthogonal images do notinclude any portion of the side of the image. The 3D model (which may betextured with an oblique or street side image) would work as well. Theoperator verifies that the property and structure of interest 21 on thescreen matches the property and structure of interest 21 that he isstanding in front of to ensure that the operator generates the properreport.

The operator then clicks on the structure of interest 21 and requests aflight plan for that structure of interest 21. Software, running oneither or both of the user terminal 14 and the host system 12 thenisolates the structure of interest 21 and generates an outline asdescribed above. The software also causes the user terminal 14 system todetermine the height H of the structure, either by using an automatedmethod, or by having the operator use a height tool on the obliqueimage, such as through the method described in U.S. Pat. No. 7,424,133.This height H is then used to automatically determine the proper flyingheight, lateral offset L_(OFFSET), and vertical offset V_(OFFSET) offsetfor the flight path for the unmanned aircraft 18 (which may be anunmanned aerial system). The height H may also be used to aim thesteerable camera 19 carried by the unmanned aircraft 18.

In this embodiment, first, a “Target Path” is generated that follows thepath of the perimeter of the structure 21 and that is at a height overground such that a center C₁ of the field of view may be located atone-half the height of the structure of interest 21 as illustrated inFIG. 5. Thus, if it is a two-and-a-half story structure of 28′ height,the Target Path would be generated such that the center C₁ of the fieldof view may be at 14′ height over ground. Although, it should beunderstood that the height over ground does not have to place the centerC₁ of the field of view to be one-half the height of the structure ofinterest 21 and can vary.

Next, characteristics of the camera 19 may be used, such as, forexample, the desired effective resolution of the image as well as theoverall sensor size of the camera 19 onboard the unmanned aircraft 18,to determine the maximum vertical swath width that may be captured on asingle pass. So, for instance, if the desired effective image resolutionis ¼″ GSD, and the sensor has 4,000 pixels in the vertical orientation,then the maximum vertical swath width would be 1,000″ or 125′. Asignificant buffer B may be subtracted out to allow for position andorientation errors when flying, for buffeting due to wind, and forabsolute position errors in the reference imagery. The size of thebuffer B can vary, but can be about a 20% buffer on all sides of theimagery. As such, in this example, the maximum vertical swath widthwould be 75′. If the structure of interest 21 has a greater height Hthan this, then the structure of interest 21 may need to be captured inmultiple passes. If so, using the same example numbers above, the firstpass would be captured at 37.5′ above ground, the second at 112.5′ aboveground, the third at 187.5′ above ground, and so on until the entirestructure of interest 21 is covered.

If the structure of interest 21 is smaller than the maximum verticalswath width, then the resolution can be increased beyond the desiredeffective image resolution. So in the above example of thetwo-and-a-half story house, the resolution could be switched to ⅛″ whichwould yield a maximum swath width of 37.5′ which is more than sufficientto cover the 28′ of structure height while still including the 20%buffer B on all sides.

Once the effective image resolution has been determined, the lateraloffset L_(OFFSET) and vertical offset V_(OFFSET) can then be determinedby calculating the path length that achieves the determined resolution.For instance, with a 5-micron sensor pitch size and a 50-mm lens, thepath length would be 104′. If the desired imagery is to be captured at aΘ of 40-degrees (an angle from 40-degrees to 50-degrees down fromhorizontal is typically optimal for oblique aerial imagery) then thattranslates to a lateral offset L_(OFFSET) of 79.6′ stand-off distance(cosine of 40×104′) and a vertical offset V_(OFFSET) of 66.8′ verticalheight adjustment (sine of 40×104′).

Using the Target Path as a starting point, the path would now be grownby the requisite lateral offset L_(OFFSET) and vertical offsetV_(OFFSET) distance using standard geometry or morphological operatorsto create the Flight Path. For instance, if the target path were aperfect circle, the radius would be extended by the 79.6′ lateral offsetL_(OFFSET) distance. If the target path were a rectangle, each sidewould be extended outward by the 79.6′ lateral offset L_(OFFSET)distance. The flying altitude for the Flight Path would be determined byadding the vertical offset V_(OFFSET) distance to the height of theTarget Path and then adding that to the ground elevation for thestarting point of the flight path. So in the example of the 28′ house,the flight altitude would be the sum of the 14′ Target Path height overground, the 66.8′ vertical offset V_(OFFSET) for the desired resolution,and the base elevation at the start, which for this example will be 280′above ellipsoid. Thus, the resulting flight height would be 360.8′ aboveellipsoid.

Ellipsoidal heights are used by GPS-based systems. If the elevation dataavailable, such as an industry standard Digital Elevation Model or asthe Tessellated Ground Plane information contained in the obliqueimages, as described in U.S. Pat. No. 7,424,133, is defined in mean sealevel, the geoidal separation value for that area can be backed out toget to an ellipsoidal height, as is a well-known photogrammetricpractice. From a software stand-point, a software library such as isavailable from Blue Marble Geo can be used to perform this conversionautomatically.

Next, the software would determine Target Capture Points of the cameracontrol information. The Target Capture Points may be spaced along theTarget Path in such a manner as to ensure full coverage of the verticalstructure of interest 21. This would be determined using a similarmethod as was done with the maximum vertical swath width. Once thedesired resolution is known, it is multiplied by the number of pixels inthe horizontal orientation of the sensor of the camera 19, and thensufficient overlap is subtracted. Using the above example, if there are3,000 pixels in the sensor of the camera 19 in the horizontalorientation and the software uses the same 20% overlap and ⅛″ GSDeffective image resolution that is discussed above, then a suitablespacing distance for the Target Capture Points would be 18.75′. Thus, anarbitrary start point would be selected (typically a corner along thefront wall is used) and then going in an arbitrary direction, a TargetCapture Point would be placed on the Target Path every 18.75′ as well asone at the next corner if it occurs before a full increment. A TargetCapture Point may then be placed on the start of the next segment alongthe Target Path and this pattern may be repeated until all the segmentshave Target Capture Points.

Once all the Target Capture Points have been determined, the TargetCapture Points can be projected onto the Flight Path to create FlightCapture Points. This projection may be accomplished by extending a lineoutward from that is perpendicular to the Target Path and finding whereit intersects the Flight Path. This has the effect of applying thelateral offset L_(OFFSET) distance and vertical offset V_(OFFSET)calculated earlier. These Flight Capture Points are then used to firethe camera 19 as the unmanned aircraft 18 passes by the Flight CapturePoints. When doing so, the unmanned aircraft 18 keeps the camera aimedat the respective Target Capture Point. This aiming can be accomplishedby a number of methods, such as an unmanned aircraft 18 that can turn,but is best accomplished with a computer controlled gimbal mount for thecamera 19.

Alternatively, the camera 19 on the unmanned aircraft 18 could be putinto “full motion video mode” whereby continuous images are captured ata high rate of speed (typically greater than 1 frame per second up toand even beyond 30 frames per second). Capturing at high frame ratesensures sufficient overlap. However, capturing at high frame rates alsoresults in a much greater amount of image data than is needed whichmeans longer upload times. In addition, many cameras 19 can capturehigher resolution imagery in “still frame video” mode versus “fullmotion video” mode. But while still frame video mode is preferred from aresolution and data transfer standpoint, if the camera 19 has a fullmotion video mode, then the full motion video mode can also be used.When in full motion video mode, the unmanned aircraft 18 simply followsthe Flight Path keeping the camera 19 aimed towards the Target Path.

The unmanned aircraft 18 would follow the indicated Flight Path throughautonomous flight. There are numerous computer systems that can beconfigured as a flight management system to achieve this available onthe market today. The flight management system, either onboard, or onthe ground and communicating to the unmanned aircraft 18 through someform of remote communication, would then track the progress of theunmanned aircraft 18 along the Flight Path and each time the unmannedaircraft 18 passes a Flight Capture Point, the camera 19 would betriggered to capture a frame. Or in the event that full motion video wasselected, the camera 19 would be continually firing as it flew along theFlight Path. The position and orientation of the unmanned aircraft 18would be monitored and the camera 19 would be aimed towards thecorresponding Target Capture Point, or in the event that full motionvideo was selected, the flight management system would keep the cameraaimed towards the nearest point on the Target Path. This may beaccomplished by calculating the relative directional offset between theline moving forward on the Flight Path and the line from the FlightCapture Point to the Target Capture Point (or nearest point on theFlight Path for full motion video). This then results in a yaw anddeclination offset for the camera gimbal. Typically, these offsets aregoing to be a relative yaw of 90-degrees and a relative declinationequal to the oblique down-look angle selected above (in the example,40-degrees). However, since airborne systems are continually movedaround by the air, offsets for a shift in position, a shift due tocrabbing, or a shift in the yaw, pitch, or roll of the unmanned aircraft18 would need to be accounted for. Again, this may be done by using theforward path along the Flight Path that the unmanned aircraft 18 iscurrently on and offsetting it by the relative yaw, pitch, and rolloffsets of the unmanned aircraft 18 as measured by the position andorientation system, and then further adjusted by the relative yaw anddeclination as described above.

Once the complete circuit of the Flight Path has been completed, theflight management system may instruct the unmanned aircraft 18 to returnto its launch point and land. The operator may pull any detachablestorage or otherwise transfer the imagery from the onboard storage to aremovable storage system or transfer the imagery via some form ofnetwork or communications link. The resulting images may then be used bythe user terminal 14 and/or the host system 12 to produce a structureand damage report. Systems for producing a structure and/or damagereport are described in patents U.S. Pat. Nos. 8,078,436; 8,145,578;8,170,840; 8,209,152; 8,401,222, and a patent application identified byU.S. Ser. No. 12/909,692, now U.S. Pat. No. 8,977,520, the entirecontent of each of which are hereby incorporated herein by reference.The completed report would then be provided to the operator.

The insurance and/or valuation data set may be included within thestructure report 78 and provided to the user. For example, duringunderwriting of a home, an insurance company may be able to request thestructure report 78 on a home that is recently purchased. Theinformation within the structure report 78 may be integrated withinsurance information provided by an insurance database and used to forma quote report. The quote report may be sent to the user and/orinsurance company. Alternatively, the structure report 78 may be solelysent to the insurance company with the insurance company using theinformation to formulate a quote.

In another example, the structure report 78 may be used in an insuranceclaim. In the case of a catastrophe of a customer, one or more databasesmay be used to provide an insurance dataset with claim information inthe structure report 78. For example, an insurance database having apolicy in force (PIF) and a weather database may be used to correlateinformation regarding an insurance claim for a particular roof. Thisinformation may be provided within the structure report 78.Additionally, in the case of loss or substantial alterations to thestructure 21, multiple images may be provided within the structurereport 78 showing the structure 21 at different time periods (e.g.,before loss, after loss). For example, FIG. 9 illustrates an exemplaryscreen shot 86 of the structure 21 having with an image 88 a captured ata first time period (e.g., before loss), and an image 88 b captured at asecond time period (e.g., after loss).

Real estate and/or census data sets may also be including withinstructure report 78.

Other services related to structure may be provided within the structurereport 78. For example, using the square footage of the roofingfootprint, a price quote may be generated on the cost of insulation forthe roof (e.g., energy efficiency, insulation replacement, and thelike). Additionally, audits may be performed using information withinone or more databases. For example, using the roofing area of astructure, historically paid insurance claims for comparables, andvalidation of payment for a specific claim for the home, a comparisonmay be made to determine whether the service payment for the specificclaim was within a certain threshold. Auditing, it should be understood,may be applied to other areas as described herein as well.
